摘要

提出了一种基于梯度投影迭代(GPI)法的多波长高温计(MWP)真温检测独立检索计算算法。它的优点是不需要预先假设发射率方程，实现对所有光谱通道的光谱发射率识别。对6种典型发射率分布材料进行了GPI模拟，检索结果表明，即使输入5%的随机噪声，真实温度相对误差也小于1.5%，abs误差小于30K。同时光谱发射率也得到了相似的相同分布。

An Independent Retrieval Algorithm of Multi-wavelength Pyrometer

An independent retrieval computing algorithm for true temperature detection of multi-wavelength pyrometer (MWP) is explored based on gradient projection iteration (GPI) method. Its advantage is no assumption equation of emissivity in advance to realize the spectral emissivity recognition for all spectral channels. 6 kinds of typical emissivity distribution materials is simulated by proposed GPI, the retrieval result shows that the true temperature relative error is lower than 1.5% even if the 5% random noise is input, abs error is lower 30K. Meanwhile the spectral emissivity also is obtained the similar identical distribution.
